Police said Monday that no one has been arrested in the weekend gunfire. Sgt. Jesse Salame said investigators are trying to determine what prompted the dispute that broke out before dawn Sunday that left five people wounded.

Officials said four men and one woman were being treated for injuries not believed to be life-threatening.

Police said the gunfire broke out after two men allegedly not invited to the party showed up. Authorities believe one of the men got into an argument, pulled a gun and opened fire — then both men fled.
